I need to match 4 of these, it looks like a 351 and 390 to me. Any guidance on the correct part would be greatly appreciated.

Hi Andrew,

Yes, this does appear to be either the S351-28 or the S390-28. To confirm which of them is the correct series, you'll need to measure the depth of your bottom shoe.

Comparison of the S351 and S390 balance shoes.

Once you've confirmed the series, you'll need to look at the back of the balance for the stamp. If your balance does not have one, you'll need to obtain the exact weight of your sash. There is a chart below the product description that lists the weight ranges each stamp can support.
